NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 624,161, dated May 2, 1899.

Application filed February 10, 1898. $erial No. 669,828. (No model.)

in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a simple, cheap, and efficient non-refillable bottle; and the invention consists of the several details of construction and combinations of parts hereinafter fully described, and particularly pointed out in the claim.

'In the accompanying drawings, Figure 1 is a sectional View of a portion of a bottle embodying my invention. Fig. 2 is a perspective View of one of the valves employed in carrying out my invention; Fig. 3, a section of the same Fig. 4, a perspective view of a check-valve; Fig. 5, an end'view of the same; and Fig. 6, a sectional view of the bottle-neck, the valves being removed.

Similar reference-letters indicate similar parts in the several figures.

A indicates the body of the bottle, and Z) its neck. The upper end of the neck formsa cork-receiving chamber a, and at the bottom of this chamber the bore of the neck is reduced, thereby forming the shoulder a and a valveehamber 062. At the bottom of the chamber a the bore is still further reduced to form the conical valve-seat a and the valve-chamber 00*, which communicates with the interior of the body of the bottle. Between the shoulder a and the valve-seat a an annular groove a is formed in the wall of the valve-chamber a and a bead b is formed on the exterior of the neck opposite the groove.

B indicates a valve the stem of which is adapted to fit loosely in the chamber a) in such manner that liquid can flow between it and the wall of the chamber. The head b of this valve is adapted to seat on the shoulder a and is of less diameter than the cork-chamber a. The stem of the valve B is provided with oppositely-arranged grooves b which are connected at their upper ends by an opening extending transversely through the stem. A piece of spring-wire is inserted through said transverse opening, and the end portions of the wire are bent downwardly atnearly a right angle to form the spring-arms 19 which lie partially in the grooves 12 The free ends of these arms are bent outwardly, as indicated by If, and the bent ends are adapted to be sprung into the annular groove a when the valve is in place in the neck of the bottle and will prevent the withdrawal of the valve.

0 indicates a check-valve the head 0 of which is adapted to rest on the valve-seat a and prevent entrance of liquid through the neck to the body of the bottle. The stem 0 of this valve will work freely in the valvechamber a and permit the liquid 'to flow from the bottle between it and the wall of the chamber.

After the bottle is filled the valve C will be first put in place, next the valve B, and finally the cork. To discharge the liquid, the cork must be withdrawn, and by tilting the bottle the pressure of the liquid will unseat the valves Cand B and permit the liquid to es cape, it being understood that the annular groove a is of sufficient width to permit a limited movement of the bent ends b of the spring-arms longitudinally of the neck of the bottle. The upper end of the valve 13 will be of metal or glass to prevent the insertion of an implement therein for the purpose of withdrawing it, and it is evident that as long as this valve is in the neck of the bottle the valve 0 cannot be held from its seat to permit the bottle to be filled.

Having described the invention, I claim- The combination with a bottle the neck of which is provided with a cork-receiving chamber at its upper end, a valve-chamber of less diameter than the cork-receiving chamberimmediately below the latter with a shoulder at their junction, and a second valve-chamber below the first valve-chamber of less diameter than the latter a conical valve-seat being formed at their junction and the first valvechamber having an annular groove in its wall intermediate its upper and lower ends, of a check-valve the stem of which fits loosely-in the second valve-chamber and the head of which fits in the said conical valve-seat, a second valve the stem of which fits loosely in the first valve-chamber and the head of which is of'less diameter than the cork-reoeivin g chamber and adapted to rest on the said shoulder, the said stem having oppositely-disposed longitudinal grooves connected at their upper" ends by a transverse opening, and a piece of spring-wire extending through said opening with its end portions bent to form spring-arms seated partially in said grooves, and the free ends of said arms being bent outwardly to engage in said annular groove, the groove being Wide enough to permit limited movement of the said bent ends therein longitudinally of the bottle-neck, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

HERBERT S. BLYNT.
